155960-40-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155960-40-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,9,6 and 0 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 155960-40:
(8*1)+(7*5)+(6*5)+(5*9)+(4*6)+(3*0)+(2*4)+(1*0)=150
150 % 10 = 0
So 155960-40-0 is a valid CAS Registry Number.
